[0055] Specifically, as Figure 2 , Figure 2 and Figure 3As shown, the food placing part 3 is configured as a square structure, and has a return air side wall 31 and two air inlet side walls 32, the return air side wall 31 is arranged at the rear side of the food placing part 3, and the two air inlet side walls 32 are arranged at the side of the food placing part 3, and the return air side wall 31 and the cooking fan 211 are distributed in the front-rear direction, and the two air inlet side walls 32 are distributed in the first direction, and in actual design, the two air inlet side walls 32 can be distributed in the first direction, which is beneficial to the symmetrical air inlet of the two air inlet side walls 32, wherein the return air hole 311 is arranged on the return air side wall 31, and at least one air inlet side wall 32 is provided with an air inlet hole 321, the air flow channel 12 and the inside of the food placing part 3 are communicated through the air inlet hole 321, the side air inlet of the food placing part 3 is realized, and then the air flow passes through the return air side wall 31 through the return air hole 311 to the cooking fan 211 for circulation.
[0056] Among them, the air inlet hole 321 can be arranged on one air inlet side wall 32, or the air inlet hole 321 can be arranged on the two air inlet side walls 32 respectively.
[0057] In some embodiments, the two air inlet side walls 32 are provided with air inlet holes 321, so that the two air inlet side walls 32 are communicated with the air flow channels 12 on both sides through the air inlet holes 321 arranged respectively, and the air inlet of the food placing part 3 at the two air inlet side walls 32 can be realized. And the air inlet holes 321 of the two air inlet side walls 32 can be distributed symmetrically, which is beneficial to the symmetrical air inlet of the two air inlet side walls 32.
[0058] Among them, the air flow direction is as shown by the arrow, Figure 6 、 Figure 3 and Figure 6 The hot air flow of the cooking fan 211 enters the air flow channels 12 on both sides, flows in the front-rear direction, enters the food placing part 3 through the air inlet holes 321 of the two air inlet side walls 32 respectively, so that the hot air flow uniformly fills the food placing part 3 from both sides, improves the uniformity and air inlet efficiency of the air inlet, and improves the cooking efficiency of the food.
[0059] In some embodiments, the air inlet side wall 32 is provided with a plurality of air inlet holes 321, and the plurality of air inlet holes 321 are distributed on the air inlet side wall 32 in the front-rear direction.
[0060] Among them, the air inlet hole 321 can be configured as a square, a long hole, etc., such as Figure 7 and Figure 4As shown, the air inlets 321 are multiple, and the multiple air inlets 321 are distributed in the front-rear direction, for example, the multiple air inlets 321 can be uniformly distributed in the front-rear direction. In actual application, when the first direction is the left-right direction, the multiple air inlets 321 on the two air inlet side walls 32 are symmetrically distributed in the left-right direction, so that the hot air in the air flow channels 12 on both sides can enter the cooking cavity 21 through the symmetric multiple air inlets 321, and the hot air can be uniformly distributed in the cooking cavity 21, improving the uniformity of food heating in the left-right direction, ensuring the heating efficiency of the food, avoiding over-heating and burning the food on one side, and improving the use effect of the cooking equipment 100.
[0061] Specifically, as shown in Figure 7 and Figure 4 The multiple air inlets 321 can extend in the up-down direction or in the front-rear direction, and the overall distribution is symmetrical and neat, which is simpler to process.
[0062] Therefore, by the above arrangement, the two air inlet side walls 32 are reasonably utilized to set more effective air inlets 321, and this arrangement can also achieve multiple air outlets of the hot air flow, effectively disperse the hot air flow, and the arrangement is various and can be flexibly selected.
[0063] When the first direction also includes the up-down direction, the two air inlet side walls 32 can also be distributed on the upper and lower sides of the food placing member 3, and the two up-down distributed air inlet side walls 32 are respectively provided with corresponding air inlets 321, and the air inlets 321 of the up-down distributed air inlet side walls 32 are symmetrically distributed in the up-down direction, so that the hot air in the air flow channels 12 enters the cooking cavity 21 from the upper and lower air inlet side walls 32, and the hot air can be uniformly distributed in the cooking cavity 21, improving the uniformity of food heating in the up-down direction, ensuring the heating efficiency of the food, avoiding over-heating and burning the food on one side, and improving the use effect of the cooking equipment 100. The overall distribution is symmetrical and neat, which is simpler to process.
[0064] Therefore, the food can be uniformly heated in multiple directions, the cooking effect of the food is improved, the symmetric arrangement can reduce the turbulence and resonance of the air flow, achieve the effect of noise reduction, and the overall structure is symmetrical, which is simple and fast to process.
[0065] In other embodiments, the apertures of the multiple air inlets 321 are configured to gradually increase in size along the direction away from the cooking fan 211. This increases the resistance to the hot airflow near the cooking fan 211, thereby reducing the airflow volume near the cooking fan 211, and decreases the resistance to the hot airflow away from the cooking fan 211, thereby increasing the airflow volume away from the cooking fan 211. This achieves uniform airflow volume across the entire surface of the two air inlet sidewalls 32, compensating for the uneven airflow caused by the continuous decrease in the velocity of the hot airflow during flow. This improves the airflow efficiency from the airflow duct 12 to the food placement component 3, thereby improving the cooking efficiency of the food. The structure is simple and ingenious. Furthermore, depending on the device, air inlets 321 can be provided on the sidewall of the food placement component 3 (the side near the cooking fan 211) and on the front sidewall of the food placement component 3 to adjust the airflow volume at different locations to better meet the airflow requirements.
[0066] In other embodiments, the distribution density of the plurality of air inlets 321 is set to gradually increase in the direction away from the cooking fan 211.
[0067] In this way, the distribution density of the multiple air inlets 321 on the air inlet sidewall 32 is relatively small in the area near the cooking fan 211, that is, the spacing of the multiple air inlets 321 in this area is relatively large. This can increase the resistance of airflow from the air inlet sidewall 32 into the food placement component 3 in the area near the cooking fan 211. On the other hand, the distribution density of the multiple air inlets 321 on the air inlet sidewall 32 is relatively large in the area away from the cooking fan 211, that is, the spacing of the multiple air inlets 321 in this area is relatively small. This can reduce the resistance of airflow from the air inlet sidewall 32 into the food placement component 3 in the area away from the cooking fan 211. This balances the air intake volume of the entire wall surface of the two air inlet sidewalls 32, thereby achieving uniform air intake volume across the entire wall surface of the two air inlet sidewalls 32. This can compensate for the uneven air intake caused by the continuous decrease in speed of hot airflow during flow, improve the air intake efficiency from the airflow duct 12 to the food placement component 3, improve the cooking efficiency of food, and the structure is simple and ingenious.
[0068] Furthermore, the distribution density of the multiple air inlets 321 gradually increases along the direction away from the cooking fan 211, which can make the distribution of the multiple air inlets 321 stable and change, stabilize the structure of the air inlet sidewall 32, and improve the durability of the air inlet sidewall 32.
[0069] In some embodiments, the food placement component 3 includes a return air sidewall 31, an air inlet sidewall 32, and two air guide sidewalls. The air inlet sidewall 32, the return air sidewall 31, and the cooking fan 211 are distributed opposite each other in the front-back direction. The return air sidewall 31 is provided with a return air hole 311. The two air guide sidewalls are distributed opposite each other in the first direction. An airflow duct 12 is formed between the air guide sidewall and the inner wall of the housing 1. The air inlet sidewall 32 is provided with an air inlet hole 321 that communicates with the airflow duct 12.
[0070] Specifically, as shown in Figure 7 The food placing part 3 has a return air side wall 31, two air guide side walls and an air inlet side wall 32. The return air side wall 31 can be arranged at the back side of the food placing part 3, the two air guide side walls are arranged at the side of the food placing part 3, and the air inlet side wall 32 is arranged at the front side of the food placing part 3. The air inlet side wall 32 and the return air side wall 31 are arranged in the front-rear direction opposite to the cooking fan 211, and the two air guide side walls are arranged opposite in the first direction. In actual design, the two air guide side walls can be arranged opposite in the first direction, which is beneficial to the symmetrical air inlet of the two air guide side walls towards the air inlet side wall 32. The return air hole 311 is arranged on the return air side wall 31, and the air inlet side wall 32 is provided with an air inlet hole 321. The air flow in the air flow channel 12 can enter the inside of the food placing part 3 from the front side through the air inlet hole 321, so as to realize the front air inlet of the food placing part 3, and then flow into the cooking fan 211 through the return air hole 311 for circulation.
[0071] The side and front of the food placing part 3 can also be arranged to have air inlet at the same time, so that the hot air flow can flow into the food placing part 3 from multiple sides, improving the uniformity and efficiency of air inlet.
[0072] In some embodiments, the support tray 34 is formed with air permeable holes 341, and the air inlet hole 321 is in communication with the air permeable holes 341.
[0073] Specifically, the support tray 34 is provided with air permeable holes 341, which can realize the air permeation of the upper and lower sides of the support tray 34. As shown in Figure 3 The air permeable holes 341 are uniformly and spacedly arranged on the support tray 34, and the air permeable holes 341 can be configured as long strip holes. The air inlet hole 321 is adapted to be in communication with the upper and / or lower sides of the support tray 34. In actual design, the air inlet hole 321 can be in communication with the upper side of the support tray 34, or in communication with the lower side of the support tray 34, or in communication with both the upper and lower sides of the support tray 34. The arrangement mode is various, and can be set according to the actual air inlet demand. In this embodiment, the air inlet hole 321 is in communication with both the upper and lower sides of the support tray 34. In this way, the hot air flow enters the food placing part 3 from the air inlet hole 321 through the air flow channel 12, and the hot air flow in the food placing part 3 can flow upwards and downwards through the air permeable holes 341, so as to heat the upper and lower sides of the food at the same time, improving the heating efficiency of the food.
[0074] The plurality of support trays 34 are all provided with strip-shaped air permeable holes 341, which can also be used for oil leakage. The design of the support tray 34 can not only be limited to the air fryer, but also be applicable to other kitchen equipment such as oven, microwave oven, etc. As shown in Figure 3 The bottom of the cooking cavity 21 is provided with an oil receiving tray 35, which can collect the oil of the food during cooking, facilitate cleaning, and keep the cooking equipment 100 clean and sanitary.
[0075] In other embodiments, multiple support trays 34 are spaced apart in the vertical direction, and food can be placed on at least two support trays 34 at the same time, which can increase the amount of food that can be cooked and the cooking of multiple foods.
[0076] Furthermore, the spacing between multiple support trays 34 can be the same, thus maximizing the use of limited space and allowing multiple support trays 34 to be placed simultaneously to cook more food, improve cooking efficiency, save time and energy, and make reasonable use of the internal space of the food placement component 3. In the design, the flow of hot air between each layer ensures that the food on each layer is heated evenly. The support trays 34 can be designed to be detachable and adjustable to adapt to different amounts and types of food, and the shape of the support trays 34 can be matched with the space of the food placement component 3, such as square or round, and is easy to disassemble and clean, maintaining the hygiene of the air fryer.
[0077] In some embodiments, the cooking device 100 further includes a viewing window 15 disposed on the top of the housing 1, with the first direction being the left-right direction, and the food placement member 3 is adapted to allow air to enter along the first direction or from the front.
[0078] Specifically, the viewing window 15 is located on the top of the housing 1, allowing the user to observe the cooking effect of the food in the cooking cavity 21 through the viewing window 15 on the top of the housing 1. When the first direction is left-right, that is, the airflow ducts 12 are distributed on the left and right sides of the food placement 3, side air intake of the food placement 3 can be achieved. In addition, when the airflow ducts 12 can lead to the front of the food placement 3, air intake from the front of the food placement 3, the support tray 34 is parallel to the rotation axis of the cooking fan 211, and the airflow ducts 12 are not provided on the top of the food placement 3, a complete viewing window 15 can be provided on the top of the housing 1, providing more space for observing the food cooking process to meet the user's visualization needs, and the overall structure of the cooking device 100 is safe and efficient.
[0079] Therefore, through the above settings, air can be introduced into the food placement component 3 through multiple airflow ducts 12, which can improve the heating uniformity and cooking efficiency of the food. At the same time, a viewing window 15 can be provided to facilitate the user to observe the cooking process, thus solving the problem of the viewing window 15 damaging the airflow ducts 12 and achieving compatibility between the two.
[0080] Furthermore, the viewing window 15 of the top-vented cooking device 100 can be distributed on the side of the cooking device 100.
[0081] A flow guide structure 4 is provided between the food placement component 3 and the inner wall of the cooking cavity 21. The flow guide structure 4 forms a flow guide groove 41. The high-temperature airflow at the heating component 212 is suitable to enter the flow guide groove 41 and flow from the flow guide groove 41 to the airflow duct 12.
[0082] Specifically, the flow guide structure 4 is used for deflecting the change of the air flow direction, and is arranged between the cooking cavity 21 and the food placing piece 3. The flow guide structure 4 can be fixedly connected in the shell 1. Specifically, the flow guide structure 4 can be located between the heating piece 212 and the food placing piece 3. Under the driving of the driving piece 111, the cooking fan 211 can drive the high-temperature hot air flow at the heating piece 212 to pass through the guide of the flow guide structure 4, so as to guide the hot air flow into the air flow air duct 12, and then into the food placing piece 3 to heat the food. In this way, the flow guide structure 4 can realize the flow regulation effect of the air flow, improve the flow rate of the air flow, eliminate the rotational direction speed of the air flow, make the movement direction of the air flow more controllable, avoid the high-speed and low-speed zones, and thus improve the food cooking efficiency.
[0083] The flow guide structure 4 is located between the heating piece 212 and the food placing piece 3. As shown in Figure 2 , the center of the flow guide structure 4 is the same as the center of the cooking fan 211. The flow guide structure 4 is formed with a flow guide groove 41 which can be configured as a groove or a channel. In this way, the cooking fan 211 can drive the high-temperature hot air flow at the heating piece 212 to flow to the flow guide groove 41, guide the hot air flow to flow to the air flow air duct 12 through the flow guide groove 41, and then into the food placing piece 3 to heat the food.
[0084] In this way, by arranging the flow guide groove 41, the high-temperature air flow can be better driven to enter the air flow air duct 12, and the flow regulation of the air flow can be realized. In this way, the air flow can be reasonably distributed to ensure that the food is heated more evenly during the cooking process, avoid local overheating or undercooking, and reduce the waste of heat to improve the cooking efficiency.
[0085] In some embodiments, the flow guide structure 4 includes a return air area 42 and a guide air area 43. The food placing piece 3 is provided with a return air hole 311. The return air hole 311, the return air area 42 and the cooking fan 211 are distributed in the front-rear direction.

As shown in Figure 3 , Figure 2 and Figure 5 , the food placing piece 3 is provided with a return air hole 311 on the side close to the cooking fan 211, which is used for communication between the food placing piece 3 and the return air area 42. The flow guide structure 4 can be configured as a cover structure. The return air area 42 is located in the central area of the flow guide structure 4. The guide air area 43 is located on the outer side of the return air area 42. The return air area 42, the return air hole 311 and the cooking fan 211 are distributed in the front-rear direction. As shown in Figure 8As shown, the return air area 42 is provided with a return air opening 421, and the food placing member 3 and the flow guide structure 4 are in communication along the return air path.
[0087] The return air hole 311 is opposite to the return air opening 421, so that the hot air flow enters the air flow duct 12 through the air guide area 43, and then enters the food placing member 3 to heat the food. Part of the hot air flow flows reversely through the return air hole 311 and the return air opening 421, realizing the return of the hot air flow. The hot air flow circulates repeatedly to realize continuous heating of the food.
[0088] The distance between the return air area 42 and the food placing member 3 is small or connected closely, which can make the return air distance of the hot air flow small, improve the return air speed of the hot air flow, and improve the circulation flow rate of the hot air flow.
[0089] The return air hole 311 can be configured as a circular hole, and the return air opening 421 can be configured as a circular hole, an elliptical hole, etc. The return air hole 311 and the return air opening 421 are both multiple, and the multiple return air holes 311 are uniformly spaced and distributed on the side wall of the food placing member 3. The multiple return air openings 421 are uniformly spaced and distributed in the return air area 42. The multiple return air holes 311 and the multiple return air openings 421 can be distributed circumferentially or in a square shape. The setting mode is various, and can be selectively set according to the required return air amount.
[0090] The flow guide groove 41 includes a first flow guide sub-groove 411 and a second flow guide sub-groove 412. The first flow guide sub-groove 411 is formed in the return air area 42 and surrounds the return air hole 311. The second flow guide sub-groove 412 is formed in the air guide area 43 and is communicated between the first flow guide sub-groove 411 and the air flow duct 12.
[0091] Specifically, the first flow guide sub-groove 411 and the second flow guide sub-groove 412 are both used to change the flow direction of the hot air flow, such as Figure 9 As shown, the first flow guide sub-groove 411 is located at the outer periphery of the return air area 42. The first flow guide sub-groove 411 can be configured as an arc structure and extends around the outer periphery of the return air hole 311. In this way, the hot air flow in the return air area 42 can be guided through the first flow guide sub-groove 411, avoiding the dispersion of the hot air flow and causing local overheating.
[0092] The second flow guide sub-groove 412 is located in the air guide area 43. The second flow guide sub-groove 412 can be configured as a straight line structure. One end of the second flow guide sub-groove 412 is communicated with the first flow guide sub-groove 411, and the other end of the second flow guide sub-groove 412 is communicated with the air flow duct 12. In this way, the hot air flow in the first flow guide sub-groove 411 can be guided through the second flow guide sub-groove 412 and then enter the air flow duct 12, realizing the flow guiding of the hot air flow from the return air area 42 to the air flow duct 12.
[0093] Therefore, by twice guiding, more hot air flow can enter the hot air flow air duct 12, the flow speed of the hot air flow can be increased, more heat can be delivered into the food placing part 3, the circumferential direction speed of the hot air flow can be reduced, a loop can be formed between the cooking cavity 21 and the food placing part 3, the heat utilization rate can be increased, and the heating efficiency and heating effect of the hot air flow on the food can be improved.
[0094] In some embodiments, the second guiding sub-groove 412 is provided as at least two, the at least two second guiding sub-grooves 412 are respectively communicated with the first guiding sub-groove 411, the air flow air duct 12 is provided as at least two, and the at least two air flow air ducts 12 are communicated with the at least two second guiding sub-grooves 412 one by one.
[0095] Specifically, the at least two second guiding sub-grooves 412 are respectively communicated with the first guiding sub-groove 411, that is, the air flow in the first guiding sub-groove 411 can flow into the at least two second guiding sub-grooves 412, wherein the number of the second guiding sub-grooves 412 matches the number of the air flow air ducts 12, the air flow air duct 12 is provided as at least two, and the at least two air flow air ducts 12 are communicated with the at least two second guiding sub-grooves 412 one by one, so that the air flow in each second guiding sub-groove 412 can flow into the air flow air duct 12 communicated therewith along the second guiding sub-groove 412, and the air flow of the at least two air flow air ducts 12 can be guided respectively.
[0096] Wherein, the second guiding sub-groove 412 can be two, three, four, etc., and correspondingly, the air flow air duct 12 is also two, three, four, etc., so that the air flow can be guided by each second guiding sub-groove 412 towards each air flow air duct 12, so that the air flow flows along a certain path, the effective shunting of the air flow can be realized, the air flow aggregation can be reduced, and the uniformity of the air flow flow can be improved, so as to meet the cooking effect of the food.
[0097] That is, in the cooking process, as shown by the arrows in Figure 9 , the heated hot air flow can enter the food placing part 3 from the air flow air ducts 12 on the left and right sides at the same time, or the heated hot air flow can enter the food placing part 3 from the air flow air ducts 12 on the upper and lower sides at the same time, and as shown by the arrows in Figure 3 and Figure 6 , the heated hot air flow can enter the cooking cavity 21 from the air flow air ducts 12 on the left and right directions and the upper and lower directions at the same time, and the setting modes of the three air flow directions can realize multi-side air inlet of the food placing part 3, wherein the former two setting modes can be applied to smaller cooking equipment 100, the cooking cavity 21 of such equipment is smaller, and the heating performance requirement is lower, and the latter setting mode can be applied to larger types of cooking equipment 100, which has higher heating performance requirement, and the setting mode is various, which can be flexibly selected.
[0098] In some embodiments, the air guide area 43 is formed with a plurality of air guide ribs 432 extending along the first direction, the air guide ribs 432 being configured to define the second air guide sub-grooves 412.
[0099] Specifically, the air guide ribs 432 have the functions of guiding and distributing the air flow, as shown in Figure 7 The air guide ribs 432 extend along the first direction, which is the same as the flow direction of the hot air in the air guide area 43, and the second air guide sub-grooves 412 are defined between adjacent air guide ribs 432 and / or between the air guide ribs 432 and the outer wall of the air guide area 43, the second air guide sub-grooves 412 extending along the first direction, the air flow from the first air guide sub-grooves 411 can be distributed, and the air flow can flow more uniformly along each second air guide sub-groove 412.

[0100] Therefore, by arranging a plurality of air guide ribs 432, the flow path of the hot air flow can be further refined, which helps to more evenly distribute the air flow, improves the control accuracy of the hot air flow, and thus more effectively transfers heat, and prevents the air flow from diffusing in disorder, thereby improving the cooking efficiency. And by guiding and distributing the hot air flow, the speed of the circumferential rotation of the hot air flow can be reduced, and the air flow speed on the surface of the food can be more controllable. At the same time, since the air flow does not move from top to bottom or from bottom to top, when multi-layer cooking is achieved, the situation that the uniformity of the two layers of food is different is not easy to occur, and the upper and lower layers of food can be cooked evenly. And the air guide ribs 432 can also enhance the structural stability of the air guide area 43, prevent deformation under high temperature or air flow impact, and also reduce the noise caused by the air flow, provide a quieter cooking environment, and have better use effect.
[0101] In some embodiments, the cooking fan 211 is adapted to rotate along the first rotation direction, and the communication between the first air guide sub-grooves 411 and the second air guide sub-grooves 412 is formed with an air guide protrusion 413 protruding along the second rotation direction, and at least part of the air flow at the first air guide sub-grooves 411 is adapted to flow along the air guide protrusion 413 to the second air guide sub-grooves 412, and the first rotation direction is opposite to the second rotation direction.
